弓上CTA减少对比剂剂量的临床应用研究

Aortic archabove CTA reduce contrart agent doses of clinical research

目的探讨弓上动脉检查中减少对比剂剂量的临床应用价值。方法 148例疑似颈部动脉疾病患者行低剂量对比剂弓上动脉CTA检查,将图像传输GE AW4.4工作站上进行图像分析及三维成像。结果 148例患者中,图像质量为优者126例(85.1%),图像质量为良者22例(14.9%)。结论低剂量弓上CTA明显降低了对比剂剂量(约37.5%),可清楚显示颈部动脉,图像质量可以满足临床对疾病进行准确诊断的需要。

Objective To investigate the clinical value of reducing the dose of contrast agent in the examination of aortic arch above .Methods 148 cases of suspected cervical artery disease patients with low dose contrast agent of aortic arch above CTA ex -amination, image transmission AW4.4 GE workstation for image analysis and three-dimensional imaging .Results 148 case pa-tients, image quality for instituting 126 cases （85.1%）, 22 cases （14.9%） of the image quality is good.Conclusion low dose of aortic arch above CTA significantly reduces the dose of contrast agent （about 37.5%）, can clearly show the carotid artery, im-age quality can meet the needs of clinical diagnosis of disease .
